Simultaneous pancreas-kidney (SPK) transplantation is a recommended treatment option for type 1-diabetic patients suffering from end-stage kidney disease.1 Major factors contributing to the success of SPK transplantation include improvements in surgical technique and the provision of effective immunosuppressive strategies heralded by the introduction of the calcineurin inhibitors.2 According to the International Pancreas Transplant Registry (IPTR), since the mid-1990s, the most popular maintenance therapy has been with Tacrolimus and Mycophenolate Mofetil (MMF), utilized in approximately 66% of SPK transplanted recipients. Since 1994, the proportion of pancreas recipients who received induction therapy has exceeded 70% and by that means induction therapy is used with greatest frequency for pancreas recipients than for any other solid organ recipients. That is in accordance with the registry analyses and the clinical trials listed below demonstrating the highest graft survival rates for recipients given antibody induction therapy and maintained on Tacrolimus.
